For the purposes of this discussion, I think the only thing that
matters is that it applies the change in the default face's font.

Indeed. It does for me. Could this be something specific to GTK or
the window manager?
Also, I don't understand why the initial value is 240 in the first
place. By default, "emacs -Q" creates a 80-column window, so I'd
expect window-total-width to return a value slightly larger than 80 (I
get 84 here).
So it sounds like some additional factors are at work here.
